FLEXIBLE VENTILATED UNDER-RIDGE

NET ROLL

NET ROLL, the flexible ventilated under-ridge, acts as a connection between the tiles and the ridge, ensuring the outflow of air while preventing water infiltration.

NET ROLL, the flexible ventilated under-ridge that ensures great durability

The polypropylene ventilation fabric ensures excellent adaptability during installation and the ventilation strip, which is sewn and glued to the pleated wings, guarantees that the solution remains intact during installation and continues to be effective over time.

The NET ROLL under-ridge is composed of aluminium, PP non-woven fabric and butyl tape. The pleated aluminium strips can be modelled to fit the various types of tiles or ridge tiles and adhere to them thanks to a 1.5 cm butyl band. Available in three different colours, brick red, brown and black, and in two sizes, 31 and 39 cm.
